Ingredient Notes

Butter – Use real, salted butter here. If you have a food intolerance, feel free to make substitutions as needed, but I haven’t tested anything but butter. Chocolate Chips – There are no hard and fast rules here. Use whatever kind of chocolate or flavored baking chips you’d like! When I first posted this recipe years ago, I called for half semisweet and half white chocolate. Most often I just use semi-sweet or dark these days. Toffee Bits – Toffee bits are an optional ingredient (and not shown in this batch in the photos). You can find them by the chocolate chips on the baking aisle. It’s becoming harder to find plain toffee bits, and not chocolate covered. I don’t mix them into the dough because they tend to melt and change the texture of the cookie, but rather I like to sprinkle them on top before baking.

The absolute hardest part of this is waiting for these to cool.  If you sneak out a square right out of the oven, it will be gooey and doughy and fall apart.  As they cool they continue to set up.  If you’re going to serve them before they’ve cooled all the way, I suggest putting them in a bowl with ice cream on top. Otherwise, cool completely to room temp (or even chill) and then cut into squares.   At our house we actually like to eat these cold from the fridge! The centers will be like cookie dough. These are slightly crisp around the edges, and super soft in the middle, and basically heaven in a bar. This is one of those rare occasions where I think they are even better the next day. I will often make them a day ahead of time for events. They also freeze well. Here in these photos you can see a bar cut from the center after it’s barely cooled, and on the right, the next day after chilling and cooling completely. Both insane. Perfect for a weeknight treat,  a potluck party, or breakfast. I won’t tell.

If I double this recipe do I need  bigger pan? In general, it’s best to measure out ingredients for each batch in separate bowls (but at the same time) and use a separate 9×13 pan to bake each batch. The baking times here are well-tested, but only apply to the recipe and equipment as written. Tip for a Jumbo Batch: I often 1.5x the recipe and bake in my favorite 12×17 pan. Can I make these cookie bars ahead of time? Of course! Make up to 24 hours ahead of time and leave at room temp, or wrap well in the fridge for up to a week. These also freeze beautifully. I have frozen them in a big slab and sliced when defrosting, and I have frozen them in individual pieces as well.
